In the field of biotechnology, what is DNA? A. A type of protein B. A molecule that contains genetic information C. A kind of virus D. A chemical compound 相关知识点: 试题来源: 解析 B。DNA 是一种包含遗传信息的分子。选项 A 蛋白质错误;选项 C 病毒错误;选项 D 化合物不准确。
Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. In fact, nearly every cell in a multicellular organism possesses the full set of DNA required...
DNA molecules are long — so long, in fact, that they can't fit into cells without the right packaging. To fit inside cells, DNA is coiled tightly to form structures calledchromosomes. Each chromosome contains a single DNA molecule, wrapped tightly around spool-like proteins called histones, ...

Now, what is DNA renaturation? It’s the opposite process! DNA renaturation occurs when the two single strands of a once double-stranded DNA molecule reassociate with one another — the complementary bases on each strand reform hydrogen bonds with one another, and the DNA double helix reforms....

What is the basic function of a DNA molecule in a cell? What is DNA and what are its functions? What is DNA, and what is the role of DNA? Is DNA is the only genetic material in an organism? What is the cellular structure that contains genetic DNA? What are the functions of DNA ...
this, a DNA molecule is cut into smaller pieces and then used as a template for a particular strand of RNA that has been copied from the DNA’s matching complementary strand. This RNA is then able to match up with each piece of DNA and can be read off slowly, one letter at a time...
